Parker Research Portable Magnetic Inspection Unit
The Parker Research DA-1500 portable heavy duty magnetic inspection unit (1500 Amp) provides high output AC or HWDC fields for magnetic particle inspection. Field selection is determined by using the appropriate field cable connector. Current output is infinitely variable from zero to maximum by use of the current control located on the front panel, and is indicated by the panel meter. Actual current output is determined by cable size and length.
AC magnetic fields offer the best sensitivity for detection of surface defect indications. The AC field is also beneficial for demagnetizing after inspection.
This comes in two options:
